【问题描述】：
在我工作的 ubuntu 12.04 服务器上，我使用以下命令安装了 php 的 curl 扩展：
apt-get install curl
apt-get install php5-curl
service apache2 restart
做完之后 php 停止工作
如果我请求一些 .php 页面，firefox 会尝试下载文件而不是运行脚本
经过一番研究，我发现在/etc/apache2/mods-enabled/ 目录下缺少文件链接：
/etc/apache2/mods-available/php5.conf
/etc/apache2/mods-available/php5.load
所以我运行了命令a2enmod php5 并创建了链接
但是当我吃午饭时service apache2 restart 它失败了
在/var/log/apache2/error.log 下我发现了一些类似的行：
PHP Warning: PHP Stratup: Unable to load dynamic library '/usr/lib/php5/20100525/pdo.so' - /usr/lib/php5/20100525/pdo.so: cannot open shared object file: No such file or directory in Unknown on line 0
适用于各种 esttensions。
我已验证目录 /usr/lib/php5/20100525/ 不再存在
但我找到了包含 .so 文件的目录 /usr/lib/php5/20121212/
我也看到/etc/php5/conf.d这个目录是空的，没有链接，但是所有的.ini文件都在/etc/php5/mods-available下
我的问题是：
为什么更新会造成所有这些问题？
我该如何解决？解决方案可以将引用从/usr/lib/php5/20100525/ 更改为/usr/lib/php5/20121212/？我在哪里可以做到这一点？
感谢您的帮助，对不起我的英语
更新
我已经按照 seb 的建议创建了链接
ln -s /usr/lib/php5/20121212/ /usr/lib/php5/20100525
但是当我重新启动 apache 时它失败并出现错误：
apache2: Syntax error on line 210 of /etc/apache/apache2.conf:
Syntax error on line 1 of /etc/apache2/mods-enabled/php5.load:
Cannot load /usr/lib/apache2/modules/libphp5.so into server:
/usr/lib/apache2/modules/libphp5.so:
cannot open shared object file: No such file or directory
重装php能解决问题吗？ 如果是的话，我该怎么做？ 再次感谢
更新
经过几次不成功的尝试后，我从快照恢复了虚拟机，并使用 aptitude 解决了问题。
aptitude install php5-curl

我接受了第二个解决方案并且安装成功，我只需要为 apache 2.4 调整虚拟主机的配置

也尝试安装 pdo 并进行更新？
